A method for the enantioseparation of Hexythiazox via capillary electrophoresis with conductive detection was developed.The enantiomers of Hexythiazox were baseline separated within 10 min under the following separation conditions:uncoated fused silica capillary(45 cm×75μm,i.d.),5 mmol/L NaAc+ 2 mmol/L HAc+5 mmol/L β-CD(pH=4.0)+V(methanol):V(N,N-Dimethylformamide) =8:2 as running buffer,15 kV separation voltage.The effect of running buffer,pH,the concentration of chiral selector,sepa-ration voltage and inject time were discussed in detail.A linearity was found between peak height(y) and mass concentration of Hexythiazox(x) in a range of 8.0~160 mg/L with a regression equation of y=9.4+36.8x,and the correlation coefficient was 0.996 3,and the determination limit was 1.6 mg/L.
